Suppose we are interested in estimating the interest among users in using a newly developed subscription smart phone app
Let the true adoption rate in the market segment of interest be \(\lambda\).
Let \(Y_i=1\) if user \(i\) is interested in adoption. Then \[ {\rm Pr}(Y_i=1|\lambda) = \lambda. \]

We wish to learn what plausible values of \(\lambda\) might be
